Comparative Study
Combined diltiazem and lidocaine reduces cardiovascular responses to tracheal extubation and anesthesia emergence in hypertensive patients.
Hypertensive patients exhibit exaggerated cardiovascular responses to tracheal extubation. This study was undertaken to compare the efficacy of combined diltiazem and lidocaine with each drug alone in suppressing the hemodynamic changes during tracheal extubation. ⋯ Combined diltiazem and lidocaine is more effective prophylaxis than diltiazem or lidocaine alone for attenuating the cardiovascular responses to tracheal extubation and emergence from anesthesia in hypertensive patients.

Comparative Study
Assessment of laryngeal view: percentage of glottic opening score vs Cormack and Lehane grading.
To examine the intra- and inter-rater reliability of two methods that categorize laryngeal view during direct laryngoscopy, the Cormack-Lehane grading system and a new scale, the percentage of glottic opening (POGO) scale. ⋯ The Cormack-Lehane grading system has very poor inter-physician reliability. The lack of inter-physician reliability with Cormack-Lehane grading calls into question the results of previous studies in which different laryngoscopists used this method to assess laryngeal view. The POGO score appears to have good intra and inter-rater reliability. It has several theoretical advantages and may prove to be more useful for research studies in direct laryngoscopy.

Randomized Controlled Trial Comparative Study Clinical Trial
Ramosetron vs granisetron for the prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy.
To compare the efficacy of ramosetron with granisetron for the prevention of postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy. ⋯ Ramosetron was more effective than granisetron for prevention of PONV during 0-48 hr after anesthesia for laparoscopic cholecystectomy.

Randomized Controlled Trial Clinical Trial
Tourniquet inflation during arthroscopic knee ligament surgery does not increase postoperative pain.
A double-blind clinical trial was conducted to determine the effect of inflation of a thigh tourniquet during anterior cruciate ligament repair on arthroscopic visibility, duration of procedure, postoperative pain and opioid consumption. ⋯ Inflation of a thigh tourniquet did not result in increased pain or opioid consumption after arthroscopic ACL surgery. Arthroscopic visibility was somewhat impaired in some patients without the use of tourniquet. Finally, the duration of the surgical procedure was not increased in patients where the tourniquet was not inflated during the ACL repair.
